What is Neon?

Neon, as you may have heard, is the luminous chemical element used in illuminated signs around the world. It’s also a popular hue for fashion and beauty brands looking to exude vibrance, and in general, it adds an eye-catching touch to any design project.

While most people are familiar with neon as a bright color, it’s actually quite an uncommon and versatile substance. In the late 1800s, British chemists William Ramsey and Morris Travers were the first to identify neon as an element, fitting neatly in between argon and krypton on the periodic table. Using an atomic spectrometer, they slowly evaporated liquid argon and isolated what later became known as neon gas.

It’s a very stable and nonreactive monatomic gas under standard conditions, which makes it ideal for sign-making and other applications that require long-lasting light. When energized with an electrical current, the atoms emit a bright glow due to their atomic structure. It’s like a ladder with rungs: as electrons climb higher up the ladder, they become excited, releasing energy in the form of a photon that produces a specific hue.

The illuminating properties of neon have been harnessed in all sorts of ways beyond simple signage, including detecting leaks during fracking and helping to protect groundwater from lethal contaminants. The unique characteristics of neon—its inertness, its luminosity, and the fact that it can be shaped into various shapes and forms—make it an extremely useful tool for many different industries.
